Abstract

L'INVENTION CONCERNE UN CIRCUIT PERFECTIONNE DESTINE A TRAITER DES SIGNAUX NUMERIQUES DEVANT ETRE ENREGISTRES SUR UNE SEULE PISTE D'UN SUPPORT CONVENABLE D'ENREGISTREMENT. LE CIRCUIT COMPREND UN DISPOSITIF DE CORRECTION D'ERREUR DONT LE FONCTIONNEMENT CONSISTE A INTRODUIRE LA MOITIE DE L'INFORMATION DE PARITE, PROVENANT D'UN SEGMENT PARTICULIER DE DONNEE, DANS LE FLOT DE DONNEES SE TROUVANT EN AVANT DE CE SEGMENT, ALORS QUE L'AUTRE MOITIE EST INTRODUITE EN ARRIERE DUDIT SEGMENT. AINSI, DANS LE CAS D'UNE ERREUR DUE A UNE PERTE D'INFORMATION OU A UN RACCORD, LES DONNEES ERRONEES PEUVENT ETRE RECONSTITUEES A PARTIR DES INFORMATIONS SE TROUVANT EN AVANT ET EN ARRIERE DE LA PARTIE ERRONEE. DOMAINE D'APPLICATION: APPAREILS D'ENREGISTREMENT SONORE ET VIDEO.THE INVENTION RELATES TO AN IMPROVED CIRCUIT FOR PROCESSING DIGITAL SIGNALS TO BE RECORDED ON A SINGLE TRACK OF A SUITABLE RECORDING MEDIA. THE CIRCUIT INCLUDES AN ERROR CORRECTION DEVICE WHOSE OPERATION CONSISTS OF INTRODUCING HALF OF THE PARITY INFORMATION, FROM A PARTICULAR DATA SEGMENT, INTO THE DATA FLOW BEFORE THIS SEGMENT, WHILE THE THE OTHER HALF IS INTRODUCED BEHIND THE SAID SEGMENT. SO, IN THE EVENT OF AN ERROR DUE TO LOSS OF INFORMATION OR TO A CONNECTION, THE ERROROUS DATA MAY BE RECONSTITUTED FROM THE INFORMATION BEING BEFORE AND BEHIND THE WRONG PART. FIELD OF APPLICATION: SOUND AND VIDEO RECORDING DEVICES.
